Django configuration issue - django

Question

I have installed Django and able to run the server and access the Django home page. But when I add the model class I am getting the following error in terminal.
RuntimeError: Model class myproject.urls.Board doesn't declare an
explicit app_label and isn't in an application in INSTALLED_APPS.
This is my code in settings.py
ALLOWED_HOSTS = []

Accidentally removed the urlpatterns from urls.py file. Got the issue fixed and making the urlpatterns proper
urlpatterns = [
url(r'^$', views.home, name='home'),
url(r'^boards/(?P<pk>\d+)/$', views.board_topics, name='board_topics'),
url(r'^admin/', admin.site.urls),
]
Thanks
